During the launch event of the HTC EVO 4G LTE, Sprint and HTC revealed a behind-the-scenes making of video that showed how the phone came to be from concept to device you can actually touch.

HTC has posted the video to its YouTube page today, and it’s something that I recommend everyone watch, especially if they’re into the minute details that go into making a phone. The video shows…wait…is that the new HTC EVO 3D?

The Verge noticed there’s a device that appears to have two rear cameras in the promotional video. The presence of twin cameras is a sign that it’s a 3D capable device, so we ask: did HTC and Sprint intend to make a follow-up to last year’s EVO 3D? How close were we to seeing the HTC EVO 3D 4G LTE unveiled last night instead? (Holy crap that would have been a terrible name!)

This is probably just a prototype and not necessarily a sign that we might see this phone appear someday. The video was about HTC’s design process and included the new EVO 4G LTE sandwiched between the original EVO and the 3D concept that looks sort of bloated. It’s likely HTC recognized the device just isn’t ready to be a mass market device, so it scrapped it and focused on the more feasible and appealing EVO 4G LTE.

Whatever the case, take a look at the video in question and see how the EVO 4G LTE was created. The 3D prototype pops up at the 23-second mark.
